Relationship between poly-beta-hydroxybutyrate production and delta-endotoxin for Bacillus thuringiensis var. kurstaki

Biotechnol Lett. 2006 May;28(9):641-4. doi: 10.1007/s10529-006-0029-0.

Abstract

A linear relationship between total solid concentration (TSC), delta-endotoxin production [Cry = 0.2795(TSC)-0.2472, R2 = 0.8644] and poly-beta-hydroxybutyrate (PHB) accumulation [PHB = 0.1327(TSC) + 0.3974, R2 = 0.9877] in Bacillus thuringiensis var. kurstaki HD-73 was observed. A similar correlation between delta-endotoxin and PHB accumulation [Cry = 2.1573(PHB)-1.1248, R2 = 0.9181] was found. A minimum PHB accumulation of 0.52 mg l(-1) was required before the onset of delta-endotoxin production.
